Treatment of Epilepsy
WHAT
CAUSES SEIZURES?
Seizures
occur when nerve cells discharge their electric current in an abnormal
manner, much like a "short circuit". The patient may lose
consciousness, and have shaking movements of all limbs, or smaller
attacks may occur, with just staring spells, an unusual behavior,
or movements of one arm or leg. When seizures occur again and
again, the patient is said to have epilepsy. Sometimes
seizures occur as an acute warning that there is an underlying
problem which needs attention.
We
therefore carefully investigate each case of new-onset seizures,
through neurological examination, brain scan, electroencephalogram
(EEG) and blood tests. We then treat the underlying cause, as well
as providing medical management of the seizures. Acute causes of
seizures such as these include a dramatic change in blood sugar,
stroke or brain tumor.
However,
in most epilepsy cases, there is no specific acute cause.
Instead, perhaps a minor brain injury in the period surrounding
birth or an inherited tendency toward having seizures produces the
episodes. Although persons with epilepsy may have seizures frequent
enough to be disabling, most people are relatively well between
episodes, and lead normal lives.
HOW
CAN EPILEPSY BE TREATED?
Treatment
with medications usually reduces seizure frequency or eliminates
seizures. In some cases, standard medications fail to provide control;
these cases are called intractable. At the Comprehensive
Epilepsy Center, we approach the care of these more difficult
cases through the use of sophisticated techniques. These techniques
include neurosurgical
intervention, vagal
nerve stimulation, and FDA-approved clinical
trials of new investigational antiepileptic medications not
otherwise available. At the New York Hospital-Cornell Medical Center
Comprehensive Epilepsy Center, we have had extensive experience
through clinical trials with newer agents such as gabapentin, topiramate,
tiagabine and vigabatrin.
SURGERY
FOR EPILEPSY
Neurologists,
neurophysiologists and neuroradiologists work together with other
team members to evaluate the possibility of surgical treatment
of carefully-selected intractable seizure disorders. Special
monitoring techniques, such as video-EEG telemetry,
a simultaneous recording of the patient's EEG with a video recording
of his behavior, often allow us to localize the area of the brain
"responsible" for the seizures.
Extensive
"mapping" of the brain, by neurodiagnostic imaging, neuropsychological
testing and other means, is done to ensure that the neurosurgical
approach, if chosen, is a safe and desirable option. Our neurosurgical
staff proficiently meets the needs of adults and children during
all stages of surgical intervention for epilepsy.
We
also offer a new, experimental surgery for epilepsy, called vagus
nerve stimulation, which does not involve an operation on the
brain. A small pacemaker is placed under the skin, and periodically
stimulates a nerve in the side of the neck with a low amount of
electrical current. This process can reduce seizure frequency and
severity.
HIGH
QUALITY SURVEILLANCE
The
Comprehensive Epilepsy Center is an active branch of the internationally
regarded Neurology and Neuroscience Department at the New York Hospital-Cornell
Medical Center. Individuals and families receiving care through
the Comprehensive Epilepsy Center have available to them the vast
resources of one of the country's most prestigious medical and teaching
institutions.
State-of-the-art
neurophysiologic monitoring is utilized by the Comprehensive Epilepsy
Center to guide patient treatment and progress in the neonatal and
pediatric intensive care units, adult medical and surgical intensive
care units, as well as to provide high quality intraoperative surveillance
during neurosurgery.
COMPREHENSIVE
PATIENT CARE
At
the Comprehensive Epilepsy Center, coordinated interdisciplinary
care is a priority. Physicians, a nurse clinician, social workers,
a neuropsychiatrist, language therapists, occupational and physical
therapists work together with families to provide support and appropriate
interventions for concerns such as self-esteem, sexuality, cognitive
issues, altered parenting roles, reproductive decisions and workplace
disclosure issues.
The
Comprehensive Epilepsy Center has helped organize an upcoming conference
in May 1997 on Women's Neurologic Health, to be held at the New
York Hospital-Cornell Medical Center. Issues such as childbearing,
childrearing and lifecycle changes for women with epilepsy, migraine,
multiple
sclerosis and other neurologic conditions will be the subject
of this free conference, open to the public.
A
FURTHER NOTE ABOUT CHILDREN
Many
cases of childhood epilepsy are well-controlled and have a good
outcome. Some children have a more difficult time, and the combination
of seizures, medication effects and behavioral or learning problems
requires a multidisciplinary effort where family needs are
recognized as well.
Whether
seen out-patient or in-patient, children receive expert medical
attention with an emphasis on developmental needs. Children
requiring hospitalization for monitoring, medication adjustment
or surgical management are housed in a two bedded room on constant
video-camera surveillance; parents are encouraged to stay overnight.
Children
with hard-to-manage seizures may be considered for epilepsy surgery
when treatment with anti-epileptic medication fails. Neurosurgical
intervention, even at an early age, can sometimes end frequent,
uncontrollable seizures, allowing children to maximize their potential.
Epilepsy surgery in children serves to remove the source of the
seizures, or in some cases, to disrupt pathways which spread seizures.
HORMONAL
INFLUENCES ON EPILEPSY, MOOD AND BEHAVIOR
Neuroendocrinology
is the study of how hormones interact with the brain. At the Neuroendocrine
Division of the Comprehensive Epilepsy Center at New York Hospital-Cornell,
we have particular interest in the relationships between the reproductive
steroid hormones, epilepsy and behavior. Insight into the complex
interactions between the reproductive steroid hormones (estradiol,
progesterone and testosterone) and issues such as seizure exacerbation,
mood disturbances, altered libido and fertility leads to new
treatment approaches sensitive to the needs of adolescents and adults
with epilepsy, migraine and other neurologic conditions.
Reproductive
endocrine disorders are more common among women and men with temporal
lobe epilepsy than in the general population. The temporal lobe
of the brain provides important feedback to endocrine centers in
the brain, therefore indirectly influencing the secretion of important
chemical messengers. In some individuals with temporal lobe epilepsy,
disruption of temporal lobe function may impact on this hormonal
feedback system. Symptoms experienced by affected individuals, such
as amenorrhea and infertility in women, and diminished libido and
potency in men, can be effectively treated both by controlling seizures
and by normalizing the hormonal environment.
AREAS
OF SPECIAL INTEREST
The
Comprehensive Epilepsy Center of New York Hospital - Weill-Cornell
Medical Center provides care for all patients with seizures,
no matter how complex their needs. We have a special interest
in meeting family needs, and addressing women's neurologic health
throughout the lifespan. We have active research interests, including
new approaches to the management of status epilepticus, and the
effects of epilepsy on mood and memory. The Center offers clinical
trials for several new anti-convulsants, as well as new techniques
such as vagus
nerve stimulation.
